My dog's eaten this and is ill, what is it?

Observed: 29th September 2011 By: jo_jones85

Heart shaped, veined leaves and black berries
We have a dog that has eaten this plant and is now at the vets. Can anyone help us identify it so that we know if it is causing his illness?

Species with which Black Nightshade (Solanum nigrum) interacts

If this is black nightshade, although it is often cited as poisonous, it is not (to humans at least), so I hope your dog recovers. Deadly nightshade (Atropa belladonna) is poisonous, but has single black berries, not bunches like this. The berries of woody nightshade (S. dulcamara) ripen to red.

Um ....

Solanum nigrum: contains variable quantities of toxic glycoalkaloids, including solanine.

Ripe berries usually cause mild symptoms, "but the unripe berries can cause vomiting, diarrhoea, headache, dizziness and increase in body temperature; these usually start within about eight hours. In severe cases, there can be coma and even death."

My own good wishes to the dog.

I stand corrected. If I'd read a little further, there are reports of serious human and livestock poisonings due to the green berries. Sorry!
